2. Disconnect the battery charger
(Fig. 18.B) from the mains;
3. Fit the battery (Fig. 16.A) in its housing
pressing down until you hear it click firmly into
position which ensures the electrical contact;
7.3 TOPPING UP THE CHAIN OIL TANK
IMPORTANT Only use chainsaw
oil or adhesive oil for chainsaws. Do
not use oil containing impurities so as
not to block the oil filter and to prevent
irreparable damage to the oil pump.
It is essential that you use good quality oil
to lubricate the cutting parts effectively.
Used or poor quality oil does not
guarantee good lubrication and reduces
the working life of the chain and bar.
IMPORTANT Never run the chain
without sufficient oil, this could damage the
Pruner device and compromise safety.
If the oil level is low, top up as follows:
1. Unscrew and remove the cap
(Fig. 19.A) from the oil tank.
2. Pour oil in the tank and monitor the
level on the indicator (Fig. 19.B).
3. Make sure no impurities penetrate
the oil tank when filling.
4. Screw on the oil cap and tighten it.
7.4 CLEANING
7.4.1 Cleaning the machine and the motor
After every work session, clean the machine
thoroughly to remove all dust and debris.
• To reduce fire hazards, keep the machine
and, in particular, the motor free of
leaves, branches or excessive grease.
• Always clean the machine after use with a
damp cloth dipped in neutral detergent.
• Remove all traces of humidity using
a soft damp cloth. Humidity can
generate risks of electric shocks.
• Do not use aggressive detergents or solvents
to clean the plastic parts or hand grips.
• Do not spray water onto the motor
and electrical components and
prevent them from getting wet.
• To avoid overheating and damage to the
motor or the battery, always keep the
cooling air vents clean and free of debris.
7.4.2 Cleaning the chain
Remove any traces of sawdust or oil deposits
from the chain every time it is used.
If there is excessive dirt or resin build-up,
disassemble the chain and place it in a container
with a specific cleanser for a few hours. Then
rinse it with clean water and treat it with a suitable
anticorrosive spray, before reassembling on the
machine.
7.5 CHAIN CATCHER
Check the chain catcher conditions before each
use (Fig. 1.I) and repair in the event of damages.
7.6 MACHINE AND BAR
LUBRICATION HOLES
Before daily use, remove the guard (par. 4.2),
disassemble the bar and check that machine
lubrication holes (Fig. 20.A) and guide bar (Fig.
20.B) are not clogged.
7.7 NUTS AND BOLTS
• Keep all nuts, bolts and screws tight to be sure
the equipment is in safe working condition.
• Check regularly that the
handles are fixed firmly.
8. OCCASIONAL MAINTENANCE
8.1 CHAIN DRIVE SPROCKET
Regularly check the condition of the sprocket
with your local dealer and replace it when
wear exceeds the accepted limits.
Do not mount a new chain with
a worn sprocket or vice-versa.
8.2 MAINTENANCE OF THE
TOOTHED CHAIN
To ensure that the chainsaw works
safely and efficiently, it is essential that
the cutting means are well-sharpened.
Chain sharpening is necessary when:
• The sawdust looks like dust.
• Cutting becomes more difficult.
• The cut is not straight.
• Vibrations increase.
Kickback may occur if the chain
is not sufficiently sharpened
